SFRA High Accuracy Power Transformer Winding Deformation Testing
Equipment
Introduction:
- Normally, the structure and reference of the transformer are fixed
after being made, therefore, the frequency response of each winding
will be almost the same. However, under some special conditions,
such as cut off between circles or phases during the test, cut off
or winding moved during running, or winding moved in
transportation, these conditions may change the structure of the
transformer, then the frequency response may be changed, we could
detect the deformation according to the frequency response curve.
- Our company has designed the SFRA High Accuracy Power Transformer Winding Deformation Testing
Equipment based on the idea and the advanced technique. It could draw the
frequency response curve accurately. Then we compare the curves
horizontally or vertically to detect the deformation of the
transformer.
- SFRA High Accuracy Power Transformer Winding Deformation Testing
Equipment is a powerful and sensitive method to evaluate the core, winding, and
clamping structures of power transformers, by measuring their
electrical transfer functions over a wide frequency range.
